![]() "Fred W4JLE" wrote in message ... So as I understand it, as I add more radials, my field strength should increase regardless of the elevation angle. Assuming I make all measurements at the same point. "Walter Maxwell" wrote in message ... "Fred W4JLE" wrote in message ... Walt, while this would be wonderful information if I were broadcasting during the day on 75 meters, how is it applicable to those of us who don't care about groundwave? Well, Fred, it's because it has everything to do with how much of your xmtr power is heating the ground vs how much is being radiated at whatever frequency you're using. We're not even talking about ground wave, it's how much power is radiated, period. Walt Fred, the radials affect only the efficiency of the radiator--power lost in the ground resistance vs power radiated. The take off, or elevation angle is determined by the ground conductivity external to the radial system, the poorer the ground the less power will radiate at low elevation angles. In other words, the better the ground conductivity external to the radial system the lower the elevation angle of the maximum radiation. If the conductivity was perfect at an infinite distance away from the radiator the elevation angle of the maximum radiation lobe would be zero degrees. Walt, W2DU |
